DAVID FOLB, OF NEW YORK, N. Y.

DENTAL FLASK.

To all whom it may concern.-

Be it known that I, DAVID Form, a subject of the Czar of Russia, and a resident of the city of New York, borough of Brooklyn, in the State of New York, have invented certain new and usei ul Improvements in Dental Flasks, of which the following is a specification.

My invent-ion consists of an improved construction of dental flasks as hereinafter described, reference being made to the accompanying drawings in which Figure l is a perspective view of the improved flask complete. Fig. 2 is a perspective view of the top or cover of the flask. Fig. 3 is a perspective view of the side of the improved flask complete. Fig. 4 is a perspective view of the lower part of the flask. Fig. 5 is a perspective view of the middle section of the flask. Fig. 6 is a perspective view of the only bolt used in the flask.

The top or cover of the flask consists of a plate 13, of the usual general form, having narrow ofl'set margin adapted to seat on the edges of the flask to prevent slipping back and forth.

In the center of the top plate or cover is a small circular knob or button of the usual construction to be used as a handle shown in Fig. 1 as 12.

The middle section 14, of the flask consists of the sides as is usual in flasks. To the front side of the middle section directly opposite the bolt and on the upper edge of the said middle section, is an overhanging l Specification of Letters Patent.

Application filed July 16, 1909.

Patented Sept. 6, 1910. Serial No. 508,088.

shoulder 9, leaving sulficient space between the upper edge of the middle section and the shoulder to allow the top plate or cover to slip under it and be held in place thereby. At the same end of the middle section and directly under shoulder 9, is a flange 8 which fits under the shoulder 7, on the lower section. On one side is a lug 10, which fits between two guide-lugs 11, on the lower section.

The lower section 15, of the flask, consists of the walls, corresponding to the sides in the middle section, and the bottom as is usual in flasks, but having on the front side the shoulder 7, having sufficient space between the upper edge of the lower section and the said clasp or shoulder to allow the flange 8, of the middle section to slip under it and be held in place thereby.

The bolt 6, is of the usual general form used in flasks, adapted to seat into a square slot, 16, extending vertically from the top to the bottom of the flask on its rear face.

Thus I provide a dental flask so contrived that all the parts are securely held together by means of one bolt instead of three.

I claim:

In a dental flask the combination of the lower section, having on the front side the shoulder 7; and the middle section havin the flange 8, and the shoulder 9, substantially as described.
